Title: foreground object working with a corona mat
Post by: Ventilo_01 on 2017-04-24, 12:20:55
Hi all,

Would it be possible to make the foreground object working with corona? Right now, applying a material with an alpha
in opacity slot does not work. This would be handy for post production purpose.

Thanks,

Nelaton

Hi All ! Always no way to put a foreground image in Cinema 4D with Corona ?
If someone know that, please let me know. ;-)

How does one put a 3D object behind a 2D image (the curtain)? I think this would be best done in Photoshop using masks etc.

Hi, thank's for answer, of course it's what I did in Photoshop, but I would like to do that in Corona with Cinema 4D.
Cinema 4d can do that in native render since long time, I don't understand why is so long for developper to make it work with Corona.

Hi there, are you able to share how it's done in the standard renderer? If I'm missing something, it would be good to know ;)

For make appear a foreground in C4D in native render it's quit simple, just create a material with PNG transparent in diffuse color or use a PSD file with selected layer.
Create a foreground object and assign it to the material in Frontal projection create above. After that all the 3d objects appear behind the foreground object in render.
For example if you need to make appear a plant or tree in foreground in a same picture than image background or HDRi, just create a alpha or mask or layer of it and it will be appear in first plan in render, don't need to use Photoshop. I hope than I'm enough clear, my English it's not very well. ;-)

I'm sure this can be done with Corona. Are you able to share your scene at all?
